This is an investigation of the application of hydrostatic pressure to closed die cavity forming at room temperature. Upsetting materials into a cavity first filled with a low strength matrix increases the amount of plastic deformation obtained prior to fracture. The forces necessary to deform materials in this manner can be estimated from the extrusion force and the force necessary to overcome the hydrostatic pressure.
